To all Leim/n. it may com-min Be 1t known that l', HENRY E. MAURER,

Jr., citizen-of the lnited States, residing at Springfield, in the county of Sangamon and State of Illinois, have invented a certain new and useful Improven'ient in Apparatus for Dispensing Liquid, of which the followingr isa full, clear, concise, and exact description.

My invention relates to apparatus for dispensing liquids and has a number of objects and advantages in' view.

Y One object vot' my invention 1s to provide unitary valve mechanism having a number of valve portions operated in proper order to control theadmisison of liquid to and its discharge from containers. The invention also has other Characteristics and will be fully explained by reference to the accompanying drawings in which Figure 1 1s a view, somewhat diagrammatic, illustrating the preferred embodiment of the invention, views of the valve mechanism being' ytaken on line A-A, B-B and C C of F ig. 5; Figs. 2, 3 and 4 are views, somewhat dia `grammatic, of parts illustrated in F ig. 1 showing ditferent valve adjustments; Fig. 5 illustrates a unitary valve structure embracing the valve elements shown in Figs. 1 to 4 inclusive; Fig. (3 is a view on line 6-6 of Fig. 5; and Fig'. 7 is a side view ot' parts ot' the valve structure.

Like parts are indicated by similar characters of reference throughout the different figures.

The container 1 is desirably in the lorm of an inverted glass bottle. As I have pracy tised my invention the bottle is ot live gallon capacity. `Gage marks 2, correspondinfb` to other measured. quantities of liquid within the bottle, may be suitably provided, as by means oi marks molded upon the bottle. The bottle neck 3 is received in an annular or tubular seat 4 whose bore is in direct communication with the bore of the bottle neck to aH'ord direct passage for liquid through the bottom of ithe container, the bottle neck, not only outwardly in the dispensation of the liquid trom the-container, but also inwardly to replenish'the supply of liquid within the container,

The gasolene or other liquid is supplied to' the container trom a supply tank 5 which is vented, as at 6. The liquid iows from. the tank tothe container through the hose 9 'connected .the top of the container.

structure being cure the desired control pipe 7 and Hows from the container through the eduction nipple 8 and the discharge with this nipple. The container may be drained or emptied back into the tank through the by-pass 10 that connects `the passage 3 with the pipe 7, it being desirable to do this-when the apparatus is out of service, as at night. A suction-vent tube 11 is preferably within and extends to When liquid is being. discharged from the container, this tube is thrown into communication withl the external air to act as a vent. When' liquid 'is' being passed into the container, I

this tube is thrown into communication' with the air exhaust pump 12 ortle'vacuum tank 13 in which vacuum is maintained by Said pump. I The valve 14 serves, according to its adjustment, to seal the inlet-outlet, end 3 of the container, or to establish connection between the container and the. discharge hose and then-to cut oft communication between the supply trank and container, or 'to establish connection between the container and supply t'ank and then to cut ofi' communication between the container and dischargtgehose. The valve 15, according to its adjustment, establishes or breaks` the continuity of the by-pass 10. The valve 16, according to its adjustment, establishes or breaks connection between the vent tube 11 and the external air; or establishes and breaks connection between said vent tube and 'the vacuum tank. All of said valves are formed in a .unit-ary structure, as shown in Fig. 6, such unitary preferably a single piece of brass 17 suitably ported to have it form all of the valves. the composite valve 17 operating in a single. valve casing 18, that is ported 'correspondingly to said valve. This composite valve and its casing are tapered, a spring- 19 serving' to hold the valve in snug engagement with its casing to avoid lea-kage. The valve is provided with a handle 2O having' a vspring pressed plunger detent 21 for holding the handle-and valve in the position to which it is adjusted. The handle sweeps over adial 22 having notches 23 for receiving the detent 21, these notches being positioned at the 'diii'erent-- places to which] the composite valve is tobe adjusted to and associationbf the container inlet-outlet 3., InjFig; 1. then valve handle is shown at, the notchl marked i ,sonnet Hose establishing a valve adjustment that limits the container to connection with the debi-'cry hose 9," and the external air; as clearly shown in `Fig. l.. `Whcn the valve handle is placed at the notch marked To hold the valve adjustment shown in Fig. 2 is secured. By this adjustment the container is shut ot from communi ation with the hose and the supply tank. vWhen the bottle is to be filled the valve handle is placed atI the notch marked To lill bottle" (Fig. to bring the container opening 3 into communication with the supply tank 5 and the upper end of the bottle into communication With the vacuum tank 13 by way of the tube ll to exhaust air Yfrom the upper end ci the bottle to occasion tloiv of the gasolene or other liquid upwardly into the bottle 'from the supply tank. llfhe'nithe bottle is to be drained the ."alve handle is placed at the notch marked To drain whereby the adustinent illustrated in Fig. 4 is secured. illy. this adjustment the tube l1 is thrown into communication with the external air and the continuity oi the b y-pass l() is t-ahlished7 whereupon all ot the liquid remaining in the container is discharged through the pipe 7 back into the tank The tube ll `is connected vwith the valve chamber 2l. A Hoa-t 25 is located within the valve chamber and carries the valve 26 for engagement With the seat 27 when connection with the vacuum tank 13 is to bc cut oli', this valve being separated trom its seat when communication between the container and the vacuum tank is to be established. When the container is about .filled a small portion of the liquid will flow down- `Wardly through the tube ll into the valve chamber and when received in sufficient quantity Within this chamber the fioat 25 will rise to engage the ,valve Q6 with its seat :27 whereby communication between the vacuum tank and the container is automatically cut ol? to cause thecessation of upward flow of liquid 'from tank 5 Vinto the container. Thel small portion of liquid remainin4 the valve chamber 2e and the tube 11 at the conclusion of each lilling operation is sm'iiciently sucked 'back into' the container to lower the neat as the liquid comes to its normal upper level, whereby the valve 26 is automatically opened to permit the valve 16 to function.l f
